APUs – Auxiliary Power Unit generators

CSDs – Constant Speed Drives

Components for air- and oil-cooled generators

DC Starter/Generators up to 200 KW.

Upgrading to the K738XL configuration brings the following benefits to K738 users:

K738XL promotes testing efficiency and accuracy using fully automatic, semi-automatic, and manual system control.

K738XL extends the useful life of the K738 at a reasonable cost.

K738XL eliminates obsolescence issues and insures long-term operation and factory support by using an Industry Standard computer and software platform.

K738XL reduces overall support costs by using common system training and a single spare parts pool.

Compatible with existing adapter hardware saving new adapter costs.

Installation costs are minimal as K738XL utilizes a majority of the existing interconnect wiring.

Avtron continuously strives to insure that our test equipment users receive maximum value from their important investment. The K738 Test Stand has proven to be a good value and extremely reliable. To insure that current K738 users continue to receive value from their Avtron test stand, Avtron has developed an updated control and data acquisition system for all K738 test stands: The K738XL (eXtended Life). Rather than wait until our customers are inconvenienced with operating problems due to component obsolescence, Avtron is taking a proactive approach to solving this industry-wide situation. The K738XL upgrade does not require changes to CSD adapters currently in use.
The K738 Test Stand’s control and data acquisition capability, a function critical component of the test stand, is based on the Intel 8085 microprocessor. This technology was the early version of today’s modern Pentium computers. The Intel 8085 computer is no longer manufactured or supported by Intel or any other supplier. This means that any older test systems based on this hardware must be upgraded or faces discontinued use due to obsolescence. The areas of proven performance on the K738 will be retained (i.e. heavy duty motor and gearbox, heavy duty load bank, etc.) The areas affected by obsolescence will be replaced with modern control and data acquisition systems.

Avtron proposes to replace the K738 Control console and various system electronic control modules with a K938 style control console and Programmable Logic Controllers (PLC's) respectively. This upgrade will modernize the K738 to today's modern computer hardware and software standards. This upgrade, combined with the robust K738 hardware, will extend the useful life of the K738. Spare parts obsolescence will be a thing of the past.
